Thanks for your answer
!I finally found the documentation on usr/doc
I read there that i must use pnpdump > isapnp.conf : I did that and in that file (isapnp.conf) I saw my sound card opl3sax(wasn't there before)and it was only my sound card not another device.The next step says that I should uncomment the # to my sound card I/O , dma and IRQ so I did that too . But now they say to modify rc.modules (I think) so the kernel could load something related to my sound card (I believe isapnp was between them but I m not sure): I m an newbie
and I don t know what to write there ) so if somebody could give me an advice i ll be grateful.
Thanks again!
P.S.I have isapnptools installed : I took them from the slackware site and then aplied installpkg to them.I had Red Hat installed too : I used sndconfig and my sound card were installed there,but it was an old edition (with an old kernel).
